ADC-318A - ETC

ADC-318A 8-Bit/ 120MHz and 140MHz Full-Flash A/D Converter

The ADC-318 and ADC-318A are 8 bit monolithic bipolar, full flash A/D converters. Though they have high, 120MHz (ADC-318) and 140MHz (ADC-318A), sampling rates, their input logic level, including the start convert pulse, is TTL, ECL and PECL compatible. Digital outputs are also TTL compatible and allow a straight output or a programmable 1:2 de-multiplexed o.
